from (page 19 onwards)
http://www.lpt.rwth-aachen.de/Studium/Vorlesungen/Prozessfuehrung/V orlesung/SS04/Vorlesung3_notes.pdf

cut and paste the above link as it is.

At http://www.pc-pid.com you can download a free beta release of their new PC-based multiloop PID controller software.

Their software contains examples of PID controllers configured as split-range, cascade, ratio, master/slave, etc.

A simulated tank load is included with the software to help you become familiar with the different PID configurations and tuning.

Hope this helps,
Warren

Thank you, I need information about theory of Split Range Control, because is to install a program system in a Bisulfite plant.
